Document Type and Number:
Japanese Patent JP5637356
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a water-level detecting device for preventing abnormal ignition which can occur due to a water film formed for a flame hole after the inside of a heat source is submerged.SOLUTION: A water-level detecting device 1 comprises a support member 20, a rotation member 21, a hinge formation member 22, and a detecting device 23. The detecting device 23 comprises a float member 25 that moves up or down as the water level increases or decreases. When the water level is at or over a certain value and the float member 25 moves a certain distance upward vertically, the rotation member 21 rotates via the hinge formation member 22 to maintain the posture of the float member 25. After that, even when the water level decreases to less than the certain value, the posture of the float member 25 is maintained, whereby the occurrence of abnormal ignition can be prevented.
